The Schedule referred to ln these Letters Patent and making part of the same.

To all 'whom t may concern y Be it known that we, SAMUEL H.SHEPLAR, of

San Francisco, California, and WLLLIAM G. CoNK-.

LIN, of Portland, county'of Multnomah, State of O1'- egon, have linvented au Improved Seed-Sewer; and we do hereby declare the followirig description vand accompanying drawing aresuicient to enable any person skilled in the art or science to which it most nearly appert-ains to make and use our said invention or improvement without further invent-ion or experiment.

Our invention relates to an improved revolving seed-sower for sowing small grains, such as4 wheat; and f It consists of `a perforated cylinder, made in two parts.

The gra-in is fed into each of these parts by means of a hopper, which is placed between the two, a peculiar trough serving to divide the grain as it-falls from the hopper, and convey it equally into both ends of the cylinder.

yIn each part or end of this cylinder is fixed a spiral flange, which serves to convey the grain toward the ends and equally distribute it, so that the sowing will be evenly accomplished at every portion of the length of thecylinder.

In order to more fully illustrate and describe our invention, reference is had to the accompanying drawing forming a part of this specification, in which- A and B are two cylinders, similar in construction.

These cylinders consist of an inside and an outside cylinder, both being provided with corresponding openings, a a, of any suitable shape The inner cylider m of each can be turned so as to lessen the vsize of the openiugs'or entirely close them, as desired, and locked in either position by means of the pin b and ratchet d.

Inside of both of these cylinders is a flange, C, which is secured spirally to the sides, and extends from one end to the other,vserving to distribute the grain equally to all parts of the cylinder.

One end of each of these cylinders is closed'aud the other is open, so that they can be both united with a middle cylindrical section, D, upon which the hop'- per E is placed.

The section D is provided with closed ends, leaving a `ange, e, projecting outward, inside of which lthe forming, as it were, a continuous cylinder. i Inserted in the section D, directly -beloW the hopper, is a short scoop-shaped trongh,'E, into which the grain falls from the hopper, and by means ot' which it is equally distributed to the two cylinders A and B, or two inclined scoops or chutes might' be used for this purpose.

The cylindersA and B and the section D are united by a rod or shaft, G, which passes through the center of each and screws into a nut, j, which is rmly secured in the ceuterofvthe closed end of one or both of the cylinders.

This device, when put together, is to be placed upon some suitable vehicle, and the middle section D iirmly secured to it. A belt can then be passed around theA axle of the vehicle, and then around Uthe pulley g on the end of the shaft Cr, thus causing the cylingcrs A and B to be revolved. v

The grain is placed in the hopperE, 'from which it falls into the trough'E, where it is separated, an equal portion being conveyed finto Athe cylinders at each side of the vhopper. The spiral flange C then carries it along to the extreme outer ends, thus distributing it so that the sowing or scattering of .the grain will be accomplished with uniformity along the entire cylinder.

Having thus described our invention,

What we claim, and desire to secure by Letters Patent, is

1. The flange C, arranged spirally inside the cylinders A and B, substantially as and for the purpose described.

2. 4The stationary cylindrical section D, with its hopper E and distributing-trough lE', substantially as and for the purpose above described.

3. A seed-sewer, composed of two revolving cylinders, A and B, and section D, when united by a ceutral shaft, Gr, substantially-as above specified.

In witness that the above-described invention is claimed'by us,wehave hereunto set our hands and seals.
